摘　　要：近年来,国内水平井施工技术水平得到了显著提升,并且日益成熟,在矿山开发工程中应用较为广泛。但是在矿山帷幕注浆等工程中应用处于起步上升期,由于帷幕注浆工程施工中存在诸多技术性要求,因此要做好相应设计和应对措施。本文以某矿井帷幕注浆工程为例,通过对水平井施工技术应用难点、帷幕注浆工程技术要求等进行深入分析,为后期类似工程的顺利进行奠定一定理论基础。In recent years,the domestic horizontal well construction technology level has been significantly improved,and increasingly mature,in the mine development project is widely used.But in the mine curtain grouting and other engineering applications are in the beginning and rising period,because there are many technical requirements in the curtain grouting engineering construction,so it is necessary to do the corresponding design and response measures.In this paper,a mine curtain grouting project as an example,through in-depth analysis of horizontal well construction technology application difficulties,curtain grouting engineering technical requirements,and so on,to lay a certain theoretical foundation for the smooth progress of similar projects in the later stage.
